Floribunda rose plant named `JACdor`

ABSTRACT

A floribunda rose having bright red with yellow reverse flowers of high centered hybrid tea flower form, long vase life, and many small prickles on main stems and glands on peduncles.

The present invention relates to a new and distinct variety of rose plant of the Floribunda class which was originated by me by crossing the variety of an unnamed seedling, with the variety KORfarim, U.S. Plant Pat. No. 3,229.

The primary objective of this breeding was to produce a new rose variety having a flower color similar to the male parent KORfarim but with the more compact floribunda habit and dense foliage of the female unnamed seedling floribunda. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Bright red with bright yellow reverse flowers;

2. High centered hybrid tea form in a floribunda rose;

3. Long vase life for a garden floribunda rose;

4. Very glandular peduncle;

5. Many small prickles on main wood of the plant.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

I claim:
 1. A new and distinct variety of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its bright red with light yellow reverse flowers, its high centered hybrid tea flower form, its long vase life and its many small prickles on main stems and glands on peduncles.
